Let Jesus “fight” for you with his very nature, through who he is. With his Glory and with his loving Presence.
The key idea that you want to understand and be very clear about is this: every good quality, aspect or characteristic of Jesus that you can discover in Scripture or from inspiration through Holy Spirit, and every experience of Jesus where you understand his very Nature better — is part of his Glory & his Presence.
No evil can stand in or resist any aspect, nature or quality of God. No unclean spirit can exist or remain in God’s Glory — these are just too antithetical. Too different. It is impossible.
So…in the Glory or Presence of God, no devil, no demon; no evil or unclean spirit can remain – they are too opposite. Only God is bigger and more inclusive and wins every time. No evil can be equal to any nature or quality or aspect of Jesus, who is the perfect representation of our Father and who sends Holy Spirit to us.
How is this different from the promises of Psalm 91?
Go. Pray. Be secure and safe in the Presence and Glory of Jesus.
